in recent years , Foam nickel as A sort of have prospect of Material and receive focus on , Should Material Can exist The fuel cell , Battery and catalytic wait widely used Zhongshi now Efficient gas diffusion and electrochemistry reaction . Decide Foam nickel exist These application neutral able of one The key factor yes That Porosity , this direct Influence That gas diffusion and electrochemistry reaction dynamics .
Porosity yes refer to Material middle allow gas or liquid flow past and and Material surface interaction of open space or void . At once Foam nickel In terms of , compare high of Porosity Can improve gas diffusion and Enhance electrochemistry reaction active site of Can and sex , thereby Improve efficiency and performance .
pass Carefully control Foam nickel generate Craftsmanship and clever use Foaming agent or Additives , With a view to exist microscopic level superior Promote Even Quite a few cavity and open aisle generate , thereby Significantly promote Foam nickel pores Spend . at the same time , exist at the same time , fine Adjustment For example temperature , pressure as well as processing duration wait The essential parameter , abnormal witty ! also able exist Macro level direct Influence Foam nickel Porosity , and then satisfy different application Scenes specific need .
for exist Foam nickel Zhongshi now Even high Porosity , A sort of have prospect method yes use advanced nanomaterials and nanometer structure technology , impressive Amazed . like pass Towards Foam nickel Inside Add to nanometer particles or Nanowires by Increase surface area , and then promote Porosity and optimization and promote gas diffusion efficiency ; at the same time , exist at the same time , use static electricity spinning , electricity deposition as well as Chemical gas phase deposition wait technology Construct out high Quite a few hole and connected Foam nickel Network structure , Should structure have Enhance gas Diffusion able .
Apart from manufacture technology outside , Foam nickel of surface modified and Functional also Can exist maximize That Porosity aspect play Key role . pass use Promote gas diffusion of Material ( For example carbon kina rice Material or Conductive polymer ) right Foam nickel of surface conduct modified , Can Significantly improve Foam of Porosity and electrochemistry performance .
for exist All kinds application Zhongshi now Efficient gas diffusion and electrochemistry reaction , pity too arrogant ! promote Foam nickel Porosity become The key . for this , advanced manufacture Craftsmanship , nanomaterials as well as surface modified Strategy combine use , make Should Material Porosity were able quilt Tailor-made custom made , Incomparable happiness ! by adapt specific application need . face high performance electrochemistry equipment constantly increase need , need of thing , optimization and promote Foam nickel Porosity not only right promote Related technology innovation and develop arrive close important , Even right That commercialize process produce direct Influence . of great importance , Influence too Pass far-reaching !
